android - Android 中的资源$NotFoundException

Question

问题是 tv2.settext() 中的 Resources$NotFoundException，我不知道为什么我在披萨标题和计数中有一个 TreeMap。请帮忙!

调用:

for (Pizza pizza : list) {

            if(map.containsKey(pizza.title))
            {

                int i = map.get(pizza.title);
                map.remove(pizza.title);

                map.put(pizza.title, i++);
            }
            else
            {
                map.put(pizza.title, 1);
            }
          }

披萨:

public class Pizza implements Comparable<String> {

    public String title;
    public int rate;
    public String date;
    public Bitmap picture;
    public int id;
    @Override
    public int compareTo(String another) {
        // TODO Auto-generated method stub
        return this.title.compareTo(another);
    }

}

错误代码:

for (Entry<String, Integer> entry : map.entrySet()) {

            tv.setText(entry.getKey());
            tv2.setText((Integer)entry.getValue()); //Error occures here

            tv.setGravity(Gravity.LEFT);
            tv2.setGravity(Gravity.RIGHT);

            TableRow tr1 = new TableRow(this);
            tr1.addView(tv);
            tr1.addView(tv2);
            tl.addView(tr1, new TableLayout.LayoutParams(
                    LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT));
            }
        }

错误:

10-04 09:04:40.475: ERROR/AndroidRuntime(954): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x1

将 tv2.setText((Integer)entry.getValue()); 更改为

tv2.setText(entry.getValue().toString());

这样做

 TableRow tr1 = new TableRow(this);

 for (Entry<String, Integer> entry : map.entrySet()) {

        tv.setText(entry.getKey());
        tv2.setText((Integer)entry.getValue()); //Error occures here

        tv.setGravity(Gravity.LEFT);
        tv2.setGravity(Gravity.RIGHT);

        tr1.addView(tv);
        tr1.addView(tv2);
        tl.addView(tr1, new TableLayout.LayoutParams(
                LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT));
        }
    }
